Metal mold gravity casting
machine is now widely used in foundry industry, some manufacturers in the use of metal mold gravity casting machine after production castings, may find that when use the casting in the cracks.
Actually metal mold casting quality no gravity casting machine production, manufacturers in the production could be because forget will be casting directly using the corresponding processing.
Casting production after the completion of the need according to the characteristics of a corresponding processing was carried out on the castings, a technology of heat treatment is important.
Heat treatment does not change the shape of the casting and the chemical composition of the whole, but by changing the internal microstructure of castings and improve the internal quality of casting, or change the casting surface chemical composition, or improve the use performance of the casting.
Annealing heat treatment is usually used to stress, stress relieving is to eliminate the casting residual stress in casting.
In order to make the metal mold casting gravity casting machine production have a certain mechanical properties, physical properties and chemical properties, in addition to select appropriate materials and various forming process, heat treatment process is necessary.
